3. A ball is dropped and rebounds vertically to less than the original height.

For this first bounce only, sketch graphs of

(a) the velocity of the…

The ball is then thrown at an angle to the horizontal and follows the trajectory shown in the
diagram.

Mark on the diagram the directions of

(i) the acceleration vector at P,

(ii) the acceleration vector at Q,

(iii)…

(d) The mass of the ball is 0.15 kg and the initial direction makes an angle of 50° to the horizontal.
Calculate the magnitude of the momentum of the ball at Q when it is projected with an initial speed
of 15 m s­1. Neglect the effects of air resistance.…
